Abstract: In a process for preparing methacrolein by oxidation of isobutane, unreacted isobutane is absorbed from a gaseous mixture by absorption in a liquid absorbent and recovered by stripping the absorbent with nitrogen or a mixture of nitrogen and oxygen. The recovered isobutane in admixture with the stripping gas is then recycled to the oxidation reaction.

Abstract: A process for the removal of barium containing scale from anodes which comprises treating the anodes with sulphuric acid containing not more than 10 per cent by weight of water, eg by treating with concentrated sulphuric acid at ambient temperature. The invention is especially applicable to the removal of barium sulphate containing scale from oxide coated metal anodes of the type used in the electrolysis of aqueous alkali metal chloride (eg KCl) brines and wherein the brine use has been subjected to a purification stage which involves the removal of sulphate ions by the addition of barium chloride.
